The photographs shown highlight the carving under both artificial full spectrum indoor lighting and outdoors in natural sunlight to best reveal its internal fire layers. The vibrant colors within fire agates arise from the Schiller effect, like what is seen in mother-of-pearl and opals. This phenomenon results from alternating layers of silica and iron oxide that diffract light, creating the interference patterns known as fire. Optimal lighting enhances this color play, while in dimmer conditions the fire agates may appear less vivid and appear darker with a brownish hue.
